Premium Member wessie Posted November 16, 2015 Premium Member Share Posted November 16, 2015 Depends on the system you choose. If it is purpose built for the Tracer then the maker will offer guidance on any tuning needed. If you are going to buy something pretty or noisy off Ebay without any provenance of it being designed for the Tracer then good luck. It may work, it may cause the bike to run rich, lean or not at all. What is evident from posts in this forum and others by those that know their shit, few exhausts give any benefit to performance on their own. Some will reduce performance or increase fuel consumption without a remap. With a proper ECU remap you will get the full benefit of any potential performance increase and maybe improved fuel consumption. You have invested £8000 (I'm assuming you are British as you say Tracer) in a new(ish) bike. Why skimp on getting it set up right and maybe damaging the brilliant motor? I'd rather wait until I had saved up enough money to do the job properly and just enjoy the bike as it is for now. Well, actually, I will save up to pay for a decent holiday in France on my Tracer next year as the bike is fine as it is for me.

papac2000 Posted November 17, 2015 Share Posted November 17, 2015 In general, I agree with Wessie. Any COMPLETE system that has redesigned primary header tubes and a flow-through silencer and possibly no cat will certainly benefit, and likely need a remap to run correctly. That said, a chambered design like the Akra, with db killer would be as far as I would venture with the stock tune. My bike still retains the chambered stock silencer, albeit modified as it is, and a cat. Since the original front pipe is in place the AFR on the dyno was still flat as can be at 13:1, wheras I suspect sytems that deviate significantly in design would have dips or humps as the VE (volumetric efficiency) would be affected. In summary...most full systems unless specified otherwise should be complimented with a reflash. 2015 Matte Grey Modded stock exhaust, modded stock screen, modded stock seat, OEM heated grips, LED indicators, FlashTuned ECU, ZX10R shock Link to comment Share on other sites More sharing options...
jeravoy Posted November 17, 2015 Author Share Posted November 17, 2015 Im thinking of keeping the header pipes and just cutting the pipe at the sensor and adding a different end can .just a custom can with a baffle. Would this be acceptable with stock map as i have seen people doing similar to mt09's like scorpion end cans Link to comment Share on other sites More sharing options...

Would this be acceptable with stock map as i have seen people doing similar to mt09's like scorpion end cans Define what you mean by acceptable? Are you seeking views/approval on the aesthetics or whether the bike will run properly? Are you seeking more power, noise or something to reflect a pretty view as you pass the window of the carpet showroom? Without knowing on exactly which can you propose to use it's difficult to give an opinion, informed or otherwise. Mechanically, the bike is almost identical to the MT09, with a different map. If the MT09 runs okay with your desired can, without melting a piston or two then use the information from the MT09 forums to inform your decision with regards to performance. Only you can decide if you like the look. Whatever you decide, report back with a picture so we can entertain ourselves with witty repartée This signature is left blank as the poster writes enough pretentious bollocks as it is.

adjuster Posted November 18, 2015 Share Posted November 18, 2015 I need to see if the GPR I bought for the FZ09 will work with the FJ09. I think the center stand might be an issue with the muffler placement. And I have cutting tools, and know how to weld, so what's the solution? Either way, photos will have to follow.

Would this be acceptable with stock map as i have seen people doing similar to mt09's like scorpion end cans No. Unless I have read your question wrong, cutting the pipe at the sensor means you are deleting the cat, which is restrictive. Thus the exhaust flow will be more direct to the muffler outlet with very little back pressure. if you change the flow of exhaust out of an engine, you need more or less fuel to be injected into the engine. A reflash or Power Commander will make the bike run correctly. Skip. Link to comment Share on other sites More sharing options...
jeravoy Posted November 19, 2015 Author Share Posted November 19, 2015 Ok .think im going for the reflash.next thing is where to go and get ecu flashed.im in norfolk over xmas and i will be taking ecu off bike as i have torn my Achilles so no riding for 6 - 8 weeks.any good recommendations and good fair price Link to comment Share on other sites More sharing options...

And has dyno proven results for each exhaust along with countless reviews on this site alone. Link to comment Share on other sites More sharing options...
steve Posted November 19, 2015 Share Posted November 19, 2015 im in norfolk over xmas I take it you will be in Norfolk (UK), as many readers here are in North America they may take it you meant Norfolk, Virginia, USA. 'raid I don't know of anyone there, would think you'd be limited to Norwich or King's Lynn though. Link to comment Share on other sites More sharing options...
Premium Member wessie Posted November 19, 2015 Premium Member Share Posted November 19, 2015 there was a chap on Ebay, based in Leeds, Yorkshire, UK offering a mail in service - no idea if he is competent but we need a guinea pig...

Premium Member wessie Posted November 19, 2015 Premium Member Share Posted November 19, 2015 here's the seller - MT09 option not available at the moment - 100% positive feedback, none for the Tracer sale ended last week but R1 reflash gets good feedback http://www.ebay.co.uk/usr/broug_davi This signature is left blank as the poster writes enough pretentious bollocks as it is.

If there's no need to remap then its because the exhaust has the exact same flow as stock exhaust (highly unlikely). If that's the case, then you're not going to be making any more power than stock. Otherwise its all smoke and mirrors. Any exhaust will need a remap on this bike. Link to comment Share on other sites More sharing options...
